Opis:
The present study aimed to assess groundwater quality according to the water quality index (WQI) in Ali Al- Gharbi district of the Maysan Governorate in eastern Iraq. For this purpose, 10 physical parameters such as pH, total hardness (TH), magnesium (Mg2+), calcium (Ca2+), potassium (K+), sodium (Na+), sulphate (SO42–), chloride (Cl–), nitrate (NO3–), and total dissolved solids (TDSs) were examined since 2019 from 16 different locations (viz. wells). The analysis results indicated that 18.75% of the water samples were of good quality, 56.25% of them had low quality, and 25% of such samples were very poor. The WQI also varied from 69.67 and 297.6. Therefore, prior to water use, there is a dire need for some treatments, as protecting this district from pollution is significant.

Opis:
Microplastic (MP) has been a new emerging contaminant in the municipal water supply. A water treatment process is a key to producing high-quality and safe drinking water. The performance of a conventional drinking water treatment plant (CDWTP) to remove MPs is questionable. This research aimed to investigate the performance of 2 CDWTPs in East Java in removing MPs. Full-stage treatment in two CDWTPs consisted of intake, pre-sedimentation, coagulation-flocculation, sedimentation, sand filter, and disinfection units. Five L water samples were collected with a grab sampling technique in the sampling points of intake and outlet of each water treatment unit. MP abundance and characteristics in each sample were determined using a Sunshine SZM-45T-B1 stereomicroscope and a Nicolet i10 FTIR spectrophotometer. Total MP removal efficiencies in CDWTPs I and II were 66 and 62%, respectively. The coagulation-flocculation unit performed the highest MP removal efficiencies (56%). The MP with 1–350 μm size achieved lower removal efficiencies (33–53%) than that with 351-<5,000 μm size (53–76%). The removal efficiencies of fiber, fragment, and film in the CDWTPs were 61–65%; 86–100%; and 100%, respectively.

The purpose of the study is a scientific and theoretical substantiation of the energy characteristics of ultra and nano filtration, which directly depend on the quality of the source water, to ensure reliable and uninterrupted operation of a combined water treatment plant (CWTP), to obtain high-quality drinking water in water supply systems intended for settlements and industrial facilities. The developed method of combined operation of a water treatment plant is based on membrane technology, the efficiency of which directly depends on the preliminary improvement of the quality of purified low-mineralized water using an energy-efficient membrane, post-treatment and subsequent disinfection. Indicators of the quality of treated water that meet regulatory requirements and indicators of improving the energy efficiency of the water treatment plant have been investigated and calculated on the basis of experimental data. The results of studies on low-mineralized water made it possible to obtain TDS (Total dissolved solids) with a total residual concentration of hardness and chlorides in the range of 0.77 mg/dm3 without any problems. The proposed combined water treatment plant method is a priority among fundamental and applied works in the field of water treatment, it is intended for the purification of natural waters under conditions of increased anthropogenic loads on natural water sources.

Opis:
Untreated alum sludge from Surabaya water treatment plant (WTP), which contained high concentration of alum was directly discharged into Surabaya River. It might cause problems because of the accumulation of aluminum in the lower part of the river. Alum could be recovered from the drinking water sludge using the electrolysis method. Aims of this study were to determine the optimum pH and electrical current for electrolysis using carbon-silver electrodes to recover aluminum coagulant from the sludge, and to determine the amount of the recovered alum. The sludge was acidified prior to electrolysis. Acidification was done by adding sulfuric acid at pH 3 and 4. Polarization test was conducted at 100, 200, and 300 mA, in order to determine the optimum electrical current. The electrolysis was performed in one compartment batch recirculation reactor, using silver as cathode and carbon as anode for 10 hours. Values of pH were measured every hour. The precipitated matter in the cathode was weighed, and analysed by means of Inductively Coupled Plasma. The optimum conditions of the electrolysis were achieved at initial pH 3 and electrical current 300 mA. The electrolysis resulted in the highest precipitate of 2.6112 g in the cathode.

Opis:
Data acquisition and computerised analysis can be used to plan for emergencies related to important pipe networks. The objective of this study is to illustrate how GIS and hydraulic calculations may be used to reduce the impact of unexpected events, such as contamination and physical destruction and train operators for such scenarios. A case study with calibrated hydraulic calculations is used to investigate the uncertainty of the obtained information. Hydraulic conditions and contaminant transport are simulated with open source software. It is shown how GIS analysis can be utilised to find optimal solutions for flow redirection problems and shutting off portions of the network. A control system integrated network hydraulic simulation solution is described in order to make training and preparation more efficient. The investigation revealed serious deficiencies regarding the necessary input for running simulations. Contaminant transport results indicated that localisation based on computed water quality models is possible, but contains uncertainties. Data processing and simulation are shown to be a promising tool in decision support and preparation based on the applications outlined. Despite advanced databases and computerised analysis tools, collected data and dynamic simulation are not utilised to their full potential in the process of planning for emergencies. Based on the hypothetical simulation presented, further research and data collection are required to reduce the uncertainty of contaminant transport. For future research, more effort has to be put into developing simulation environments.

Opis:
Coagulant dosing control (CDC) is necessary to ensure stable treated water quality and to reduce chemical costs both in drinking and wastewater treatment plants. The rapid development in online sensors and equipment as well as control strategies has triggered a significant development in CDC. Software sensors, streaming current detectors, charge titration units, potential dispersion analyzers etc. are now successfully used. Despite the significant advancement in the introduction and use of these novel techniques, most plants still relay on simple CDC techniques like flow proportional dosing, leaving great opportunities to reduce the coagulant costs, sludge treatment costs while achieving better treatment efficiencies overall. The paper presents a novel concept to optimize coagulant dosing control in wastewater treatment plants, and an intention to develop a widely available solution using a Polish-Norwegian Research & Development venture.
Kontrola dozowania koagulantu (KDK) jest konieczna w celu zapewnienia stabilnej jakości wody, jak i obniżenia kosztów zarówno w stacjach uzdatniania wody, jak i w oczyszczalniach ścieków. Wraz z wielkim postępem w strategii i technologii tzw. czujników „online” obserwuje się również znaczny rozwój w zakresie KDK. Zdecydowanie zwiększa się zakres czujników procesorowych, czujników w ciągłym przepływie, zestawów miareczkujących do oznaczania ładunku, analizatorów despersji itp. W przeciwieństwie do znacznego zaawansowania we wprowadzaniu i zastosowaniu tych nowatorskich technik, większość oczyszczalni ciągle opiera się na prostych systemach KDK, typu ciągłego dozowania proporcjonalnego, nie uwzględniając wielkich możliwości redukcji kosztów zużycia koagulantu i obróbki osadów, które istotnie wpływają na efektywność pracy oczyszczalni. Praca niniejsza przedstawia nowatorską koncepcję optymalizowania dawki koagulantu w oczyszczalniach ścieków oraz możliwości rozszerzenia dostępności tych rozwiązań w Polsce poprzez Polsko-Norweską Instytucję Naukowo-Rozwojową.

Opis:
Twenty groundwater samples were collected and then examined for physical (pH, EC, TDS) and chemical (Na+, K+, Ca2+, Mg2+, HCO3−, Cl−, SO42−, NO3) parameters, followed by multivariate statistics to determine the current state of groundwater quality and to assess the suitability of these resources for drinking and irrigation purposes in the Baser Sakhra area localized in Eastern of Algeria. The analysis carried out showed that the cations trend in most of the groundwater samples is on the order of Ca2+˃Na+˃Mg2+˃K+ and the anions trend is on the order of HCO3-˃SO42-˃Cl-. Stabler diagram demonstrated the predominance of Ca2+- HCO3- hydro-chemical facies (80%). Moreover, the parameters, such as sodium adsorption ratio, percentage sodium, residual sodium carbonate, permeability index, Kelly’s ratio, potential salinity, and magnesium hazard were evaluated for the suitability of groundwater for irrigation. The values obtained in this investigation concluded that most of the groundwater samples are suitable for irrigation. From the other approach, the Water Quality Index (WQI) for drinking was also used in the current study. WQI ranged from 72.46 to 506.426, indicating that 40% of the samples were suitable for drinking however, 60% of them belong to the poor to unsuitable category of drinking water in terms of physicochemical properties, according to the World Health Organization norms.
